/* This file is a heavy retheme of react-datepicker's Sass as of v1.4.0
** https://github.com/Hacker0x01/react-datepicker
**
** In places where features were disabled, I've commented out the original Sass
** selectors rather than removing it so we can better understand what's changed.
** Commented out selectors that don't have properties indicate that we are not
** using those dom elements for styling of any kind. For example, react-datepicker
** has lots of pointer arrows attached to its popovers, but we choose not to render
** then in any way.
**
** Similarly, you will also find several times where we use display: none to
** completely remove extraneous UI (they had some overly obvious legends for example).
